Lab 17 Dissection Steps

Lab 17 Dissection Steps

Lab 17 Dissection Steps: ❏ Identify the pancreas (left lobe, body, & right lobe) ​ ❏ Incise the free border of the proximal portion of the descending duodenum. Use a scalpel handle to scrape away the mucosa inside the duodenum to search for/do the following: ❏ Identify the major duodenal papilla (this is where the pancreatic duct ​ ​ opens into the duodenum) ❏ 2-3cm caudal to the major duodenal papilla, identify the minor duodenal ​ papilla (this is where the accessory pancreatic duct opens into the ​ duodenum) ❏ At the cranial aspect of each kidney identify the adrenal glands (right & left) ​ ❏ Identify the kidneys (right & left) ​ ❏ Identify the hilus of each kidney ​ ​ ❏ Identify the right and left ureter(s) ​ ❏ Free the left kidney from the surrounding peritoneum, but DO NOT remove it, and do not cut its vascular attachment. Make a longitudinal incision through the lateral border to the hilus (dividing the kidney into dorsal and ventral halves). Open the kidney and identify the following: ❏ renal pelvis ❏ pelvic recesses ❏ renal cortex ❏ renal medulla ❏ pyramids ❏ renal crest ❏ renal sinus ❏ Free the right kidney from the peritoneum, but DO NOT remove it, and do not cut its vascular attachment. Make a transverse section through it at the hilus (dividing it into cranial and caudal halves) and identify the renal cortex, medulla, renal crest and renal ​ ​ ​ pelvis. ​ ❏ In the intact FEMALE specimens, identify the following: ❏ ovaries (right & left) and the proper ligament of the ovary ​ ​ ​ ❏ uterine tube ❏ infundibulum ❏ Attempt to identify the tubouterine junction ​ ❏ Re-identify the uterus (cervix, body & horns) - previously seen in Lab 16 ​ ​ ❏ Identify the broad ligament of the uterus. Identify its three parts and ​ ​ associated terms: ❏ mesovarium and the suspensory ligament of the ovary ​ ​ ❏ mesosalpinx and (attempt to see) the ovarian bursa ​ ​ ❏ mesometrium and the round ligament of the uterus ​ ​ ❏ Re-identify the parietal & visceral peritoneum (seen in Lab 16) ​ ​ ​ ​ ❏ Identify the following parts of connecting peritoneum: ❏ lesser omentum ​ ❏ hepatoduodenal ligament ❏ greater omentum ❏ omental bursa ❏ epiploic foramen ❏ mesoduodenum ❏ duodenocolic fold ❏ mesentery (mesojejunoileum) ❏ root of the mesentery ❏ mesocolon (ascending, transverse, descending) ​ ❏ Attempt to identify the ligaments of the liver: right triangular ligament, ​ ​ left triangular ligament, coronary ligament ❏ Re-identify the falciform ligament as well as the umbilical v. remnant ​ ​ ​ (round ligament of the liver) (previously identified in Lab 16) ​ ❏ Re-identify the right & left vagus nerves (previously identified in Lab 12) ​ ​ ❏ Re-identify the dorsal and ventral branches of right and left vagus nerves ​ ​ ​ ​ and also the dorsal and ventral vagal trunks ​ ​ ​ ❏ Transect the left crus of the diaphragm at the esophageal hiatus and reflect it to observe the continuation of the vagal trunks ❏ Follow the dorsal vagal trunk and note the celiac branch to the ​ celiacomesenteric plexus ❏ On the left side, identify the thoracic part of the sympathetic trunk; trace it caudally and ​ ​ attempt to identify the following branches (transect the tendon of psoas minor if needed): major splanchnic nerve, minor splanchnic nerve, and lumbar splanchnic ​ ​ ​ ​ ​ ​ ​ nerves ❏ Identify the celiacomesenteric plexus & ganglia (and its component parts): ​ ​ ❏ Identify the celiac plexus and the right & left celiac ganglia ​ ​ ​ ❏ Identify the cranial mesenteric plexus and the cranial mesenteric ​ ​ ​ ganglion ❏ Identify the caudal mesenteric plexus & ganglion ​ ❏ Identify the right & left hypogastric nerves (be careful, these tend to ​ ​ break easily!) .
